Abstract
The invention discloses a composite water treatment agent. The composite water treatment agent consists of 0.3 to 45 weight parts of permanganate, 0.3 to 45 weight parts of ferrate, 1 to 10 weight parts of sodium silicate or 0.1 to 1 weight part of periodate, and 10 to 30 weight parts of sodium hydroxide or potassium hydroxide based on the weight of pypocholoride solution at the mass percent concentration of 10 to 30 percent. According to the composite water treatment agent, permanganate is combined with ferrate, the synergistic effect between the permanganate and the ferrate is fully exerted, the defects of the permanganate and the ferrate are eliminate, the capacity of removing ammonia nitrogen, organic matter, manganese ions, odor and chromaticity in water is enhanced, a water treatment effect is greatly improved, and water treatment cost is reduced. The prepared mixed solution can be stored stably for a long time, a process is simple, and the agent is convenient to use, and improves water treatment safety.
Description
Technical field
The present invention relates to a kind of water technology, particularly a kind of composite water treatment medicament and preparation method thereof.
Background technology
Along with China people economic activity is frequent day by day; Receive soil erosion, production and sewage more and more serious to the pollution that water body causes; Its pollutant component comprises multiple micro quantity organic pollutant, and the heavy-metal pollution thing also contains the macromole natural organic matter of higher concentration.The simple increase coagulant charging quantity that relies on can not be dealt with problems.Organic and inorganic polymer coagulant aids (as gathering propionic acid amide, activated silicic acid etc.) is though can be through increasing the flco size to the adsorption bridging effect of taking off between steady colloidal solid; Reach the purpose that increases heavy speed, improves separating effect, effect is obvious aborning, but takes off steady colloid for difficulty; Ammonia nitrogen; The heavy metal ion problem that exceeds standard, high molecular effect is relatively poor relatively, and treatment effect is not obvious.Conventional water technology is described in the face of low-temperature and low turbidity, complicated problems such as micro quantity organic pollutant, heavy metal ion exceed standard, and stink is serious, it is unable to do what one wishes to have seemed, can not adapt to the variation of current water quality.
Summary of the invention
The technical problem that the present invention will solve is the deficiency to prior art, has proposed strong, the safe composite water treatment medicament of effect of a kind of stable performance, adsorption-flocculation.Another technical problem that will solve of the present invention is a kind of preparation method who has proposed this composite water treatment medicament.
The technical problem that the present invention will solve realizes through following technical scheme; A kind of composite water treatment medicament; Be characterized in: with mass percent concentration is that 10%-30% hypochlorite solutions is ground mass part; Be equipped with the permanganate of 0.3%-45% weight part, the perferrate of 0.3%-45% weight part, water glass or the periodate of 0.1%-1% weight part and the sodium hydroxide or the Pottasium Hydroxide of 10%-30% weight part of 1%-10% weight part, said hypochlorite solutions is chlorine bleach liquor or potassium hypochlorite solution; Said permanganate is potassium permanganate or sodium permanganate; Said perferrate is potassium ferrate or Na2Fe04; Said periodate is sodium periodate or potassium periodate.
The technical problem that the present invention will solve can also realize that further said permanganate accounts for 10%-20% of hypochlorite solutions gross weight that said perferrate accounts for 10%-20% of hypochlorite solutions gross weight through following technical scheme.
The technical problem that the present invention will solve can also realize that further the two ratio of perferrate and permanganate is 1:1 through following technical scheme.
Another technical problem that will solve of the present invention realizes that through following technical scheme a kind of preparation method of above-mentioned composite water treatment medicament is characterized in: in hypochlorite solutions, slowly add sodium hydroxide or Pottasium Hydroxide; Stir, after 45 ~ 70 minutes, in above-mentioned mixing solutions, slowly add perferrate and permanganate successively; Stir, wait fully dissolving after, slowly add water glass or periodate again; Stirred 15 ~ 30 minutes, leave standstill half a hour after, filter and promptly to get.
In the preparation process, the temperature of mixing solutions is controlled between 15 ℃-25 ℃.
The present invention compared with prior art can be according to the requirement of handling different quality, with permanganate and perferrate by different ratios mixing coupling; Improved the ability of reply different quality greatly; Give full play to the synergy between them, eliminated deficiency separately, strengthened the ability of removing ammonia nitrogen, organism, mn ion, stink and colourity in the water; Improve the water treatment effect greatly, reduced cost of water treatment.
The mixing solutions of the present invention's preparation has and can steady in a long-termly preserve, and process method is simple, characteristics easy to use.Compare than the simple perferrate that uses, strengthened the effect of absorption, flocculation, strengthened the ability of de-iron demanganize,, significantly reduced cost of water treatment particularly to the removal ability of mn ion; Compare than the simple potassium permanganate that uses, improved removal effect, particularly to the removal ability of ammonia nitrogen turbidity, colourity, CODMn and UV254 and ammonia nitrogen.Reduced in the use the accurate degree of dosage requirement, be not easy to produce the colourity problem that exceeds standard, improved the security of water treatment.
Embodiment
A kind of composite water treatment medicament; With mass percent concentration is that 10%-30% hypochlorite solutions is ground mass part; Be equipped with the permanganate of 0.3%-45% weight part, the perferrate of 0.3%-45% weight part, water glass or the periodate of 0.1%-1% weight part and the sodium hydroxide or the Pottasium Hydroxide of 10%-30% weight part of 1%-10% weight part, said hypochlorite solutions is chlorine bleach liquor or potassium hypochlorite solution; Said permanganate is potassium permanganate or sodium permanganate; Said perferrate is potassium ferrate or Na2Fe04; Said periodate is sodium periodate or potassium periodate.
Said permanganate accounts for 10%-20% of hypochlorite solutions gross weight, and said perferrate accounts for 10%-20% of hypochlorite solutions gross weight, and the consumption of above-mentioned permanganate and perferrate is best amount ranges.
When the two ratio of perferrate and permanganate is 1:1, most effective.When the two ratio of perferrate and permanganate was 3:2, the water treatment versatility was best.
A kind of preparation method of above-mentioned composite water treatment medicament slowly adds sodium hydroxide or Pottasium Hydroxide in hypochlorite solutions, stir, after 45 ~ 70 minutes; In above-mentioned mixing solutions, slowly add perferrate and permanganate successively, stir, wait fully dissolving after; Slowly add water glass or periodate again, stirred 15 ~ 30 minutes, leave standstill half a hour after; Filtration promptly gets, and in the preparation process, the temperature of mixing solutions is controlled between 15 ℃-25 ℃.
The present invention relates to the water treatment agent of tap water and waste water, especially relate to the insoluble low-temperature and low turbidity of conventional water treatment process, micro quantity organic pollutant, heavy metal ion exceed standard; The water technology that stink is serious, the adaptibility to response of different quality is strong, treatment effect good because face, and process method is simple; Safe and reliable; Easy to use, characteristics such as less equipment investment are fit to water factory and undergo technological transformation very much.
